Repairing and refueling satellites robotically may seem rather mundane, especially when compared with moon landings, Mars rovers and the Hubble space telescope, but NASA's two-year Robotic Refueling Mission (RRM) experiment, now underway on the International Space Station (ISS), turns out to be surprisingly complex. Designed to demonstrate that servicing working satellites with remotely-controlled robots is a feasible option, NASA, in conjunction with the Canadian Space Agency (CSA), initiated the first of several RRM test tasks just a few days ago and the results look very promising.
